I'm trying to get MUSB Host working on my 3530 platform (very
similar to the Beagle).  When I startup, I get this message:
  Clock usbhost_48m_fck didn't enable in 100000 tries

What does this mean?  How do I fix it?

Currently, the USB subsystem finds the various hubs (ports 0-2).
The OTG port (0) works great.  When I plug in a device to USB-1,
it sees it, but immediately gives up :-(
    ehci-omap ehci-omap.0: GetStatus port 1 status 001803 POWER sig=j CSC CONNECT
    hub 1-0:1.0: port 1: status 0501 change 0001
    hub 1-0:1.0: state 7 ports 3 chg 0002 evt 0000
    hub 1-0:1.0: port 1, status 0501, change 0000, 480 Mb/s
    ehci-omap ehci-omap.0: port 1 full speed --> companion
    ehci-omap ehci-omap.0: GetStatus port 1 status 003801 POWER OWNER sig=j CONNECT
    hub 1-0:1.0: port 1 not reset yet, waiting 50ms
    ehci-omap ehci-omap.0: GetStatus port 1 status 003002 POWER OWNER sig=se0 CSC
    hub 1-0:1.0: unable to enumerate USB device on port 1
    hub 1-0:1.0: state 7 ports 3 chg 0000 evt 0002
    hub 1-0:1.0: hub_suspend
Then it's dead.  Any ideas?

Thanks
